Gaetuli

The Gaetuli were a Berber tribe which inhabited a large desert region south of the Atlas Mountains, bordering the Sahara. The Gaetuli inhabited Algeria and southwestern Tunisia, and they wore skins, lived on meat and milk, and manufactured purple dye which became treasured by the Romans during the reign of Emperor Augustus. In 3 AD, the Roman Empire defeated the Gaetuli, and a revolt by the Gaetuli was crushed in 17 AD.
